Hi Jeremiah and list, > Since people with undersized logfiles will come out on top, how about > comparing current SCNs instead?
Nice catch, but when distributed databases are involved, the following applies: Internal Operations Each committed transaction has an associated system change number (SCN) to uniquely identify the changes made by the statements within that transaction. In a distributed database, the SCNs of communicating nodes are coordinated when: * A connection is established using the path described by one or more database links * A distributed SQL statement is executed * A distributed transaction is committed Among other benefits, the coordination of SCNs among the nodes of a distributed database system allows global distributed read-consistency at both the statement and transaction level. If necessary, global distributed time-based recovery can also be completed. All databases in a 'distributed' (i.e. connected) environment will co-ordinate with each other to bump up their SCNs to the highest value+ whenever a distributed SQL is involved. So, a large DSS type database that has a relatively lesser number of queries/commits (and thus a lower SCN rate) may have its SCN count bumped up by a short-query, active OLTP... Not to mention parameters such as COMMIT_POINT_STRENGTH that could influence this... The point is that this would probably not be a good measure of the 'activeness' of a database. Btw, the v$database view will show this part of x$ktuxe. Be sure to set numwidth to a larger value. > Also longest time since last startup would be interesting to see. Now this would be an interesting one!
